ANDROID & IOS:-
The two most widely used mobile operating systems in the world are Android and iOS. They act as the building blocks for creating and utilising apps for use on portable devices, such as smartphones and tablets. An overview of each platform is provided below:
Android:-
1. Android is an open-source operating system created by Google that is based on the Linux kernel. It offers a framework that is adaptable and adjustable for creating mobile applications.
2. Programming languages like Java or Kotlin are typically used to create Android apps, while the Android Native Development Kit (NDK) also supports other languages like C++.
3. Developers can create applications tailored for Android devices using the tools, libraries, and APIs available in the Android Software Development Kit (SDK).
4. he Google Play Store and other third-party app stores are two places where Android apps can be obtained. The Google Play Store, which provides a huge selection of apps, games, and other digital content, is the main app marketplace for Android smartphones.
5. Programming Language: Java or Kotlin are typically used when developing Android apps. Due to its contemporary syntax, improved safety features, and seamless interaction with already existing Java codebases, Kotlin has become more and more popular in recent years.
6. The official Integrated Development Environment (IDE) for Android development is called Android Studio. It offers a full suite of tools for developing, testing, and deploying Android applications.
7. The Android Software Development Kit (SDK) is a set of software libraries, tools, and APIs that programmers can use to create Android applications. Access to many gadget features, including the camera, sensors, storage, and network connectivity, is made available.
8. Designing the user interface for Android apps involves combining KOTLIN or JAVA code with XML-based layouts. To build UI components, Android Studio offers a visual layout editor and enables responsive layouts for various screen sizes.
9. For testing and debugging Android applications, Android Studio includes a number of built-in tools. Using frameworks like JUnit and Espresso, developers may carry out unit testing, integration testing, and UI testing.
IOS:-
1. iOS is a closed-source operating system created by Apple that is only available for iPhones, iPads, and iPod Touches.
2. Programming languages like Swift or Objective-C are typically used to create iOS apps. Due to its contemporary syntax and performance advantages, Swift has emerged as the language of choice for iOS programming.
3. Developers can access Apple's iOS Software Development Kit (SDK), which comes with Xcode (an integrated development environment), testing simulators, and a number of frameworks and APIs.
4. The Apple App Store is the only place where iOS apps may be downloaded. To guarantee the calibre and security of the programmes made available to iOS users, the App Store has tight criteria and a review procedure.
5. Swift is primarily used in iOS app development as the programming language. Apple created Swift, a cutting-edge, quick, and secure language, especially for the development of iOS, macOS, watchOS, and tvOS.
6. The official Integrated Development Environment (IDE) for iOS development is Xcode. A complete set of development tools, such as an editor, simulator, debugger, and interface builder, are included.
7. The iOS Software Development Kit (SDK) offers the libraries, frameworks, and APIs required to create iOS applications. Access to functions like the camera, GPS, accelerometer, and iCloud connection are provided.
8. Designing the user interface for iOS apps involves using Interface Builder, a visual tool found in Xcode. The drag-and-drop capabilities of Interface Builder combined with Swift coding allow developers to construct interfaces.
9. App testing and debugging tools are available in Xcode for iOS applications. The XCTest framework allows developers to create unit tests, while the XCTest UI framework allows them to test user interfaces. Additionally, Xcode comes with tools for performance profiling and debugging.
NOTES:- React Native, Flutter, and Xamarin are a few examples of cross-platform frameworks and technologies that allow developers to create code once and release it on both the Android and iOS platforms. These frameworks typically allow varied degrees of code sharing and platform-specific customisation and employ JavaScript, Dart, or C# as the primary programming languages.
